Thanks for sharing.
We personally track CD57 and c4a for all of us. I've been tracking it for several years now (for the oldest kid) and rest of us for various years.
Our CD57s are like little bunnies... jumping all around (but they consistently stay low). The highest was once around 70, if I recall. But normally, they have been much lower than that.
I've found the c4a to be more helpful in tracking progress and changes in our health - personally.
I'm still dreaming for healthy CD57/c4a for all of us someday.
Kid#1: Extremely sick for several years, very difficult to treat, but much better lately!
Kid#2: Very sick now despite being treated for years, very bad year
Kid#3: Doing great, minor relapse, but great again (ironically had least and shortest treatment)!
Me: Adv Labs positive 2016 (suspected I passed to my kids) - not as sick as others, mostly battling fatigue, kidney, heart, and yeast issues
